Abstract

The boundary element method is adapted to 2-D electric field analysis in the vicinity of HV transmission lines of alternating current. The influence of buildings placed near the line and the irregular shape of the ground are taken into account. A double-layer mathematical model of the buildings is proposed. The material parameters are expressed by the effective complex permittivity. A direct BEM formulation with the elimination of interzonal normal derivatives is employed and the appropriate boundary integral equations are derived, The computational results of the electric field distribution near the 400 kV transmission line are presented
